Signs Your DPF May Be Blocked

Not sure if your DPF is the issue? Here are some common symptoms:

  • DPF warning light on the dash
  • Vehicle is in limp mode
  • High fuel consumption
  • Loss of power or acceleration
  • Frequent or failed DPF regeneration attempts
  • Excessive smoke from the exhaust
  • Strong diesel smell from the exhaust
  • Rising engine oil level

If you’re experiencing any of these, your DPF may be heavily blocked and in need of a professional clean.

Our DPF Cleaning Process – Step by Step

Step 1: DPF Must Be Removed First Your DPF must be removed by a certified mechanic before our technician arrives. Once your garage has confirmed the removal date, please contact us to book your clean so we can coordinate the service around your schedule.

Step 2: Initial Endoscope Inspection We carry out a detailed internal inspection using a digital endoscope to check for damage such as cracks, melting, or contamination that could affect cleaning results.

Step 3: Back-Pressure Test (Pre-Clean) We measure airflow restriction to assess how blocked the filter is from soot and ash buildup. This helps us tailor the cleaning cycle to the filter’s condition.

Step 4: Industrial Deep Clean Using Water & Chemicals The DPF is placed into our specialist machine and thoroughly cleaned using high-pressure water and DPF-safe chemical agents designed to break down compacted soot and ash inside the filter structure.

Step 5: Brief Drying Cycle After cleaning, the DPF goes through a brief drying cycle to reduce internal moisture. Some residual dampness may remain and will naturally clear after refitting and use.

Step 6: Back-Pressure Test (Post-Clean) We repeat the back-pressure test to confirm that the filter is clear and airflow has been significantly restored.

Step 7: Final Endoscope Inspection A second inspection is carried out to ensure the filter is clean, dry, and free from any remaining internal residue or visible damage.

Step 8: Post-Fitting Final Steps (By Your Mechanic) After refitting the filter:

  • Take the vehicle for a light drive (approx. 10 minutes) to complete the drying process naturally through exhaust temperature and flow
  • Use diagnostics to reset the ECU and confirm the vehicle recognises the cleaned DPF
